Do you have a 3rd party anti-virus installed on your PC?

Click your Start Button, type regedit and hit Enter to open the Registry Editor.
Click View and make sure 'Address Bar' is turned on.
Paste this into the Address Bar at the top and hit Enter.
HKLM\SOFTWARE\Policies\Microsoft\Windows Defender
Please provide a screenshot of that Registry Editor page.
Thank you for the screenshot, there is no problem indicated in your registry.
Click your Start Button, then just type Powershell and on the resulting list, right click PowerShell and select 'Run as Administrator'.
Paste this command into Powershell and press Enter:
HKLM\SOFTWARE\Policies\Microsoft\Windows Defender" /f; Set-MpPreference -UILockdown 0
Paste this command into Powershell and press Enter:
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
When that completes, paste this command into Powershell and press Enter:
Add-AppxPackage -Register -DisableDevelopmentMode "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml"
Close PowerShell and restart (not shut down) your PC
I have restart my PC already but it still cannot
Thank you for that information, if that process did not resolve this, the best option to resolve this will be to perform an in-place repair with the Windows 11 ISO.
Please ensure you download the ISO in the same language as you use for the Windows UI, follow the steps, this is then not like re-installing Windows, it is just like an update and your personal files, settings and installed software will not be affected.
Click this link:
https://www.microsoft.com/software-download/windows11
to download the Windows 11 ISO
When the ISO file completes downloading
Disconnect from the Internet
Disconnect all external devices with the exception of a mouse or keyboard.
Temporarily disable any 3rd party Anti-virus you may have installed
Then, in Windows File Explorer, double click the ISO and then run Setup.exe and select the Install option.
Very Important - ensure you select the option to keep your files and apps.
Open administrative Command Prompt.
Try executing these commands one-by-one and press Enter key:
reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKLM\Software\Microsoft\WindowsSelfHost" /f
reg delete "HKLM\Software\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender" /v DisableAntiSpyware
reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKCU\Software\Microsoft\WindowsSelfHost" /f
reg delete "HKCU\Software\Policies" /f
reg delete "HKLM\Software\Microsoft\Policies" /f
Restart your system, instead of shut down.
P.S. If you're new to Command Prompt, try creating System Restore prior to above steps.
